Answer:
b = (d-c)/a
Step-by-step explanation:
ab + c = d
We want to solve for b, so we need to get b alone
Subtract c from each side
ab+c-c = d-c
ab = (d-c)
Divide each side by a
ab/a = (d-c)/a
b = (d-c)/a
Answer:

Step-by-step explanation:
add the no. of red marbles and blue marbles
2+4 = 6
Probability so divide 6/8 simplified to 3/4
First simplify the square roots:

Then simplify the last two terms:

Since 61 is prime, you can't take a rational root out of it.
